How to Sell Your Book on Amazon and Other Platforms

Publishing a book is not the same as selling one. The authors who understand how retail platforms actually work — and what makes a book findable, credible, and buyable — sell significantly more copies than the ones who don’t.

The Bookshop That Never Closes

There is a version of bookselling that used to require relationships with physical retailers, a distributor willing to take your title, and shelf space that was competed for and rarely guaranteed to a first-time author.

That version still exists. But alongside it, an entirely different infrastructure has grown up — one that is available to every author regardless of who their publisher is, where they live, or whether a chain bookshop has ever heard of them.

Amazon continues to dominate book distribution, accounting for 50 to 80% of US book sales, with over 300 million print books sold annually on the platform. Even with the growth of ebooks and audiobooks, physical books remain in high demand. Amazon

Those numbers matter. They mean that for most authors, Amazon is not one channel among many — it is the primary channel, the one whose mechanics deserve the most careful attention and the most deliberate strategy.

But Amazon is not the only channel. And for authors who understand how each platform works, the combination of Amazon, Kobo, Apple Books, Barnes and Noble, and direct sales creates a distribution ecosystem capable of reaching readers in every market, in every format, at every price point.

Here is how to use it properly.

Amazon KDP: The Foundation of Your Digital and Print Distribution

Kindle Direct Publishing — Amazon’s self-publishing platform — is the starting point for most independent authors, and for good reason. It provides access to the world’s largest book retailer, in both print and digital formats, with no upfront cost and a straightforward royalty structure.

In 2025, over 34% of ebooks sold in the United States were through Amazon, making it a genuinely lucrative platform for independent authors. Amazon provides two primary royalty options — 35% and 70%. The 70% royalty rate applies to ebooks priced between $2.99 and $9.99. For a book priced at $9.99, the author earns approximately $6.99 per sale after Amazon’s cut. Bebold Digital

For print books, the economics work differently. With KDP royalty changes that took effect in June 2025, print books priced below a certain threshold receive a lower royalty rate. Pricing print books at $9.99 or above maintains the higher 60% royalty rate rather than the reduced 50% rate. Understanding this threshold before setting your print pricing prevents the unpleasant discovery of lower-than-expected royalties after the fact. AmzScout

Publishing on KDP is free. Amazon deducts printing costs — approximately $4 to $6 for a standard paperback — and delivery fees from your royalties. Optional costs include professional editing, cover design, and marketing. AmzScout

The free-to-publish model is genuinely accessible. But the authors who treat it as a complete production solution — relying on KDP’s basic tools for cover design and interior formatting — typically produce books that look exactly like what they are: quickly assembled, without professional production standards. The platform’s accessibility is an opportunity. The quality of the finished book is still entirely the author’s responsibility.

Optimising Your Amazon Retail Page: The Work That Actually Drives Sales

Getting your book listed on Amazon takes an afternoon. Getting your Amazon retail page to actually convert browsers into buyers is a different and more sustained effort — one that separates authors who list their book from authors who sell it.

The title and subtitle are the first and most important metadata elements. For non-fiction especially, a subtitle that clearly communicates the book’s specific promise is not decoration — it’s searchable text that determines which reader queries the book appears in.

The book description is your retail page’s sales copy. It needs to do in a few paragraphs what a great back cover does in a glance — create the specific kind of curiosity that makes the right reader decide to buy. Most authors write descriptions that summarise the book. The ones that convert readers write descriptions that sell the experience of reading it. There’s a significant difference.

Keywords and categories determine where Amazon places the book in its discovery ecosystem. Amazon’s sales algorithm weights factors including sales velocity, customer reviews, and keyword optimisation. Books with higher sales and positive reviews are more likely to be featured in Amazon’s recommendations, increasing their visibility. A study found that ebooks with at least 50 positive reviews saw a 15% increase in sales. Bebold Digital

Keyword research for Amazon involves identifying the specific search terms readers in your genre use — not the terms the author would use to describe the book, but the terms a potential reader would type into a search bar when looking for something to read. Tools like Publisher Rocket or K-Lytics help with this research. The investment is modest. The effect on discoverability is real.

Categories deserve strategic attention too. Amazon’s ranking algorithm weights recent sales velocity heavily, so strategic promotional pushes can help. Targeting smaller subcategories is often more achievable than ranking in broad categories. A book ranked in the top twenty of a specific subcategory displays a bestseller badge that influences purchasing decisions even when the reader doesn’t consciously register it. Choosing categories accurately but strategically — where the book genuinely belongs but where the competition is manageable — is worth the time it takes. AmzScout

Amazon Ads: Paid Visibility That Works When the Page Is Ready

Amazon offers cost-per-click advertising including Sponsored Products, Sponsored Brands, and Sponsored Display. These ads draw attention to listings using specific keywords and can significantly boost visibility for authors willing to invest in paid promotion. Threecolts

Amazon Ads work on a simple principle: when a reader searches for a keyword your ad is targeting, your book appears in sponsored results. You pay only when someone clicks. Whether that click converts to a sale depends entirely on how compelling your retail page is when they arrive.

This is why retail page optimisation comes before advertising spend. Paid traffic to a weak page wastes budget. Paid traffic to a strong page — compelling description, strong reviews, a cover that signals genre correctly, appropriate pricing — generates a measurable return.

For authors just starting with Amazon Ads, Sponsored Products campaigns targeting comparable authors and genre-specific keywords are the most accessible entry point. The learning curve is real but manageable, and the data generated by initial campaigns provides useful intelligence about which keywords and which comparable authors actually drive traffic to your specific book.

Pricing Strategy: The Numbers That Shape Everything

Pricing affects discoverability, perceived value, royalty income, and competitiveness — simultaneously. Getting it right requires understanding all four dimensions rather than optimising for one at the expense of the others.

For ebooks, the $2.99 to $9.99 range that qualifies for the 70% royalty is the relevant pricing window for most commercial fiction and non-fiction. Within that range, genre conventions matter significantly. Readers in certain genres have strong price expectations — romance readers are accustomed to lower ebook price points; business book readers expect to pay more. Research what comparable books in your specific category are priced at before setting your own price.

Reviews build trust — good customer feedback leads to increased visibility and more transactions. Dynamic pricing using automated tools helps capture seasonal demand spikes and maintains competitive positioning around market changes. Threecolts

For print books, the pricing calculation involves the printing cost, the royalty rate, the retail price, and the competitive landscape. A print book priced significantly above comparable titles in its category needs to justify the premium visibly — through production quality, format, or the author’s established reputation. A book priced significantly below comparable titles raises questions about quality rather than creating a bargain impression.

Pricing is not a one-time decision. The right price at launch may not be the right price six months later. Authors who revisit their pricing periodically — in response to market changes, competitive movements, or the accumulation of reviews that justify a price increase — manage their retail presence more actively and typically see better long-term results.

Beyond Amazon: Building a Multi-Platform Distribution Strategy

Amazon dominates the book market, but it is not the entire market. A significant proportion of readers buy books elsewhere — through Apple Books, Kobo, Barnes and Noble, Google Play, and through direct sales on author websites — and authors who distribute only through Amazon leave those readers unreachable.

Apple Books reaches iOS users who make their purchases from within the Apple ecosystem. It is the dominant ebook platform in certain international markets and among certain demographics. Distribution through Apple Books is handled either directly through Apple’s platform or through aggregators like Draft2Digital or PublishDrive.

Kobo has a particularly strong user base in Canada, the UK, and several European markets. Authors with readers in these geographies leave meaningful sales on the table by not having a Kobo presence.

Barnes and Noble Press reaches the significant proportion of US book buyers who prefer shopping with America’s largest physical bookshop chain, in both print and digital formats.

Google Play Books is often overlooked but reaches a very large global Android user base — readers who encounter books through the Google search ecosystem, which can be significant for non-fiction books whose topics are actively searched online.

The mechanics of managing distribution across all these platforms simultaneously are simplified by aggregators — services that distribute to multiple platforms from a single upload. Draft2Digital and IngramSpark are the most widely used. IngramSpark in particular provides access to the Ingram distribution network, which reaches physical bookshops, libraries, and international retailers in a way that direct Amazon distribution cannot.

Production quality matters differently on different platforms. A professionally designed, properly formatted book — with a cover that competes in the retail environment of each platform and an interior that reads cleanly in every format — performs better across the entire distribution ecosystem than a book produced to a minimum viable standard. Publishers who take every stage of production seriously understand this implicitly, which is why working with a partner like Papercraft Publishers — whose production expertise spans both print and digital formats — makes the multi-platform distribution strategy genuinely viable rather than merely available.

Direct Sales: The Channel Most Authors Underestimate

Direct sales — selling books through your own website or via your email list, without a platform intermediary taking a percentage — is the highest-margin distribution channel available to authors. It is also the one that requires the most infrastructure to set up and the most audience-building effort to monetise.

The economics are compelling. A book sold directly at full retail price, with payment processing fees of 2 to 3%, generates far more per copy than the same book sold through any retail platform. For authors with an established email list or a loyal following, direct sales can represent a meaningful proportion of revenue from a well-managed launch.

The practical setup involves a payment processor — Stripe, PayPal, or a shop plugin like Shopify or Gumroad — and a fulfilment partner for print copies, or a simple file delivery system for ebooks. It requires the author to drive traffic to the purchase page rather than benefiting from the organic discovery mechanisms of a major retail platform.

For most authors, direct sales are not a replacement for platform distribution — they are a complement to it, particularly effective for launches where the author’s existing audience can be mobilised directly, for special editions or bundled offers not available on retail platforms, and for building the kind of reader relationship that drives long-term loyalty.

Reviews Across All Platforms: The Compounding Asset

Reviews are the closest thing book retail has to a self-sustaining growth mechanism. Good reviews go a long way in winning customer trust and earning more sales. Brands enrolled in Amazon Brand Registry can generate reviews through Amazon Vine, a program that provides books to trusted reviewers who can try them and share high-quality feedback. Threecolts

Beyond Vine, the most reliable source of reviews is readers who are genuinely asked for them. A note in the back matter of the book — a brief, genuine request asking readers who enjoyed it to leave a review — generates a measurable proportion of reviews from satisfied readers. An email to the list after a reasonable reading window produces more.

Reviews on Goodreads perform a different function from retail reviews. Goodreads is a discovery platform — readers actively browse it looking for recommendations, and a book with a strong Goodreads presence gets recommended more often than one without. Cultivating Goodreads reviews alongside Amazon reviews covers both the conversion and the discovery dimensions of the review ecosystem.

The compounding nature of reviews is worth understanding. A book that launches with fifteen reviews builds to fifty reviews more quickly than a book that launches with two. Each review improves algorithmic placement, which drives more sales, which generates more reviews. The authors who invest in early review generation — through advance reader copies, launch team members, and direct reader outreach — build the compound curve sooner.

Metadata Maintenance: The Long-Term Visibility Strategy

Most authors set their metadata once at launch and never revisit it. This is a missed opportunity that becomes more costly over time.

The words readers use to search for books in a given genre shift gradually. New comparable authors emerge whose names become useful targeting keywords. Subcategory competition changes. Platform algorithm updates shift the weighting of different metadata elements.

Authors who review and refresh their metadata periodically — adjusting keywords, reconsidering categories, testing different description copy — maintain their discoverability over a longer period than authors who treat metadata as a one-time task. The revision requires modest effort but produces measurable results in retail platform performance.

The description in particular benefits from periodic review. A description written before launch was written with limited information about how readers actually describe the book, what they find most compelling about it, and what language they use in their reviews. A description revised six months after launch, informed by the actual reader response in reviews, is almost always more effective than the original.

The Production Quality That Makes Everything Else Work

A sophisticated distribution strategy, a well-optimised retail page, a carefully built review foundation, and a multi-platform presence all share one dependency: a book that is good enough to justify the attention they bring to it.

The cover that doesn’t signal genre correctly sends the wrong readers to the page. The interior that isn’t properly formatted produces complaints in reviews. The print book that looks self-published in the bad sense generates reader disappointment that shows up as negative word-of-mouth regardless of how clever the marketing around it was.

Authors who used KDP saw an average increase in earnings of 25% compared to those who sold solely through traditional channels — but that advantage is realised only when the book being sold meets the quality standard that retail platform visibility brings readers to expect. Bebold Digital

Professional production — a cover designed for the genre, an interior formatted to a publishable standard, print quality that rewards the reader who holds the physical book — is the foundation that all the distribution and marketing strategy is built on. Papercraft Publishers’ custom publishing services exist precisely to deliver that foundation — providing the production quality that makes every distribution channel the author accesses work harder for them.

Selling Is a System, Not a Moment

The authors who build sustainable book sales understand something that first-time authors often don’t: selling a book is not a launch event. It is a system — a combination of distribution, optimised retail presence, review generation, metadata maintenance, marketing activity, and production quality — that runs continuously and improves over time.

The launch matters. But sales velocity, customer reviews, and keyword optimisation play significant ongoing roles in Amazon’s algorithm — books with consistent sales momentum and positive reviews are more likely to be featured in recommendations, increasing their visibility in a self-reinforcing cycle. Bebold Digital

Building that cycle — getting all the system’s components working together — takes time and attention. But it is replicable. The authors who build it once, with one book, have the template for doing it faster and better with the next one.

When you are ready to publish a book with the production quality, the professional presentation, and the distribution capability to compete properly in every channel it enters — Papercraft Publishers is the publishing partner that makes it possible.

The platforms are there. The readers are there. The system is yours to build.
